The process of double fertilization is the

  • A
    Fusion of two male gametes with one egg
  • B
    Fusion of one male gamete with two polar nuclei
  • C
    Fusion of two male gametes for pollen tube with two different eggs
  • Correct answer
    D
    Syngamy and triple fusion

Solution

Double fertilization is a phenomenon unique to angiosperms. Each pollen grain produces two sperm; Of the two sperm cells, one sperm fertilizes the egg cell, forming a diploid zygote (syngamy); the other sperm fuses with the two polar nuclei, forming a triploid cell that develops into the endosperm (triple fusion) Together, these two fertilization events in angiosperms are known as double fertilization.

Hence, the correct answer is option: 'D'.
